Abstract :
We have developed an on-board 47-GHz phase locked oscillator (PLO) for millimeter-wave personal satellite communications system. For low phase-noise operation, we developed an osciplier using PET gate bias control technique, and used a sampling phase detector. We developed a noise addition model for accurate design. The phase noise of this 47-GHz PLO was an exceptionally low ¿63, ¿85, and ¿100 dBc/Hz at offset frequencies of 100 Hz, 1 kHz, and 100 kHz.
